Physics Chain — Submit Transaction

Physics Blockchain — Proof of Harmonic Convergence.

• Protocol ID — chain-submit
• Category — Blockchain
• Endpoint — POST /api/chain/tx/submit
• Auth — api-key
• Rate limit — 30/min
• Version — 1.0
• Precision — ≤0.1% (KO42-enforced)

What it does

Submit a transaction to the Physics Blockchain. Transactions are equation-signed (Zeq Auth) and carry optional physics computation data.

Signature

Request

POST /api/chain/tx/submit

Param	Type	Required	Default	Description
sender	string	✓	—	Sender ZID.
receiver	string	✓	—	Receiver ZID.
data	object	✓	—	Transaction payload.
signature	string	✓	—	Equation-derived signature.

Response

{ txId, zeqondStamp, pendingInCycle, estimatedConfirmation }

Runnable example

curl -sS -X POST \
  -H "Authorization: Bearer $ZEQ_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "sender": "<value>",
  "receiver": "<value>",
  "data": {},
  "signature": "<value>"
}' \
  "https://api.zeq.dev/api/chain/tx/submit"

Integrate

1. Consensus trigger — use Harmonic Convergence pulse phase as the block-seal condition.
2. Audit trail — write ledger entries with zeqond plus error_pct for provable determinism.
3. Fork detection — split fork handling on pulse-phase disagreement to drop stale branches fast.

Seeds

• Near — wrap /api/chain/tx/submit in a language SDK so builders can call it in three lines.
• Medium — publish a reference integration demonstrating Physics Chain — Submit Transaction alongside a real workload, with pulse-aligned metrics.
• Far — propose Physics Chain — Submit Transaction as an open reference standard so other runtimes can implement it verbatim against the Zeq paper.
